Title: Apparatus for removing the burrs from chain links welded by the electric flash butt welding method
IPC: B21L15/00
Filed: 1965-11-12
Abstract: 1,128,029. Broaching. BECKER-PRUNTE G.m.b.H. 12 Nov., 1965 [17 Nov., 1964], No. 48178/65. Heading B3L. An apparatus for removing the burrs from chain links welded by the electric flash butt welding method comprises a knife consisting of two halves 7 and 7a which in the closed position form a ring enclosing the welded side of the chain link, each knife half being carried by a tong arm 6, 6a and the arms being mounted on a slide 5 which is driven by an hydraulic, pneumatic or crank drive. The arms 6, 6a are connected by a tension spring 8 and are controlled in their inward movement by cams 11 and 11a which co-operate with roller followers 9 and 9a. The position of each roller relative to the arm is adjusted by a bolt 21 or 21a. The arms 6 and 6a are each keyed to a bolt 14, Figs. 2 and 3 (not shown), which is freely rotatable in an upper cover-plate 15 at one end and at its other end screws into a bush 16 which is rotatable in a lower cover 19. Disc springs 17 and 18 provide a resilient connection between the bush 16 and the cover-plate 19. In operation the knife halves are positioned by rotating the bolts 14 and the depth of cut is set by adjusting the bolts 21 and 21a. The arms 6 and 6a are offset in the direction of travel of the knife so that one knife half engages the chain link and shears off the welding flash before the other knife half.

Title: Method of bending hardboard

IPC: B27H1/00
Filed: 1963-12-12
Abstract: 1,022,304. Bending hardboard. WALTER S. FRY, Ltd. Dec. 7, 1964 [Dec. 12, 1963], No. 49220/63. Heading B5L. A method of bending hardboard comprises repeatedly urging a roller against one major surface of the hardboard, thereby to bend the hardboard about a heated mandrel provided at the opposite major surface of the hardboard. The sheet of hardboard is bent to form a base upon which a similar bent sheet of thermosetting resinous laminate is bonded. The sheets are bent so as to curve upwardly at one edge zone and downwardly at another edge zone to prevent warping. The bending is effected in a machine having a hollow mandrel and a hollow roller which are heated by pumping oil therethrough at about 200‹ C. The board is laid across the mandrel and the roller is depressed into contact with the top surface of the board to bend it through a small angle, the process being repeated until the desired bending is reached, the board then being clamped to the mandrel. Cooling water may be directed to the surface of the board facing away from the mandrel while the hardboard is clamped. Alternatively, the edge zones may be immersed in water before bending.

Title: Hydraulic motor-control circuits
IPC: F15B21/042
Filed: 1965-11-22
Abstract: 1,128,222. Hydraulic control circuits; reciprocating pumps. TOYODA MACHINE WORKS Ltd. Nov.22, 1965 [Nov.25, 1964; Aug.9, 1965], No.49551/65. Headings F1A and F1P. A reciprocating hydraulic motor 1, Fig. 16, is continuously supplied with pressurized oil at uniform temperature by a feed pump, e.g. a rotary pump 78, drawing from a tank 27' thermally isolated from heat sources and directly driven from a fluid, e.g. oil, operated motor 76 supplied by an electric motor driven pump 4 drawing from a second tank 5 to which is discharged exhaust oil from the motor 76 and oil passing a relief valve 7 in the pump delivery line 89. The feed pump 78 delivers through a non-return valve 90 and a solenoid valve 8 to one or other end of the motor 1 according to which of a pair of limit switches (L.S.1, L.S.2) is closed. Relief valve 7 is controlled by pressure in the delivery line of feed pump 78 and in the supply line of motor 76. In a modification the feed pump comprises reciprocating pistons 21, 21', Fig.2, and cylinders 15, 15' arranged in parallel; the pistons being directly connected by rods 30, 30' to pistons 16, 16' of out-of-phase motors supplied from the motor driven pump 4 delivering through solenoid valves 33, 33' controlled by limit switches (L.S.3, L.S.4, L.S.5 and L.S.6) which are themselves actuated by dogs 32, 32' carried by rods 31, 31' of pistons 16, 16'. In operation and assuming the two sets of connected pistons commencing their forward delivery stroke, dog 32 and rod 31 closes limit switch (L.S.6) after about half the stroke and so reverses solenoid valve 33', so that whilst piston 21 completes its delivery stroke, piston 21' is quickly withdrawn to perform half a suction stroke at the end of which suction stroke (L.S.5) is closed, valve 33' is reversed and the slow forward delivery stroke of piston 21' is recommenced. The piston 21 in the meantime dwells at the end of the delivery stroke until dog 32' closes (L.S.3) to reverse valve 33 and so initiates the fast suction stroke of piston 21. At the end of said suction stroke, dog 32 closes (L.S.4) to initiate the slow delivery stroke of piston 21. In the meantime piston 21' dwells at the end of its delivery stroke until dog 32 closes (L.S.6) to reverse valve 33' to initiate the fast suction stroke of piston 21'. At the completion of this suction stroke dog 32' closes (L.S.5) to initiate the forward stroke of piston 21'. Thus the outof-phase reciprocation of the feed pump pistons 21, 21' ensures a continuous supply of pressure oil to the change over valve 8 controlling the motor 1. The feed pumps described with reference to Fig. 9 (not shown), are double-acting and in a further modification Fig. 12 (not shown), the motors driving the feed are operated by compressed air.

Abstract: 1360446 Power hammers WORTHINGTON CORP 3 Nov 1971 [9 Nov 1970] 51101/71 Heading B3H An hydraulic hammer has its piston 18 pressurized constantly with hydraulic fluid on its lower face and alternately connected to a fluid source or an exhaust on its upper face and the passageway to the exhaust has a Venturi so that the back pressure against the upper face during an up-stroke of the piston is maintained relatively constant. The fluid inlet 34 is connected to the hammer cylinder bore by a port 42 and through grooves 45 in the cylinder wall to the lower face 44 of the piston and by a port 46 and a slide valve 50 to the upper face 58. The chamber 56 is alternately connected to an outlet port 64 by the slide valve whose reduced diameter portion 52 has an annular projection 72 which form the Venturi with the bore 54 when the valve is open. The valve is controlled by differential pins 66, 68. The pins 66 have a smaller effective area than the pins 68 and the pins 66 are connected constantly to inlet pressure whereas the pins 68 are only intermittently connected to the inlet pressure. A by-pass conduit 80 is automatically opened by a valve 82 to connect the inlet and outlet when the tool 28 of the hammer is in its lowermost position and hence not in contact with the work. The valve 82 is operated by differential pressure on surfaces 94, 96, 98 of the valve so that if the surface 98 is connected to exhaust by an overlong stroke of the hammer the valve automatically opens. The tool 28 is held in the hammer bore by a ball 32. The tool may perform the working operations or be an anvil in contact with a separate tool. The hammer may be used in demolition work.
